LOGGlNG-CAR STAKE.

SPECIFICATION forming part of Letters Patent No.675,227, dated May 28, 1901. Application filed February 25, 1901` Serial No. 48,754. (No model.)

To @ZZ whom it may concern.-

Be it known that we, SAMUEL G. LIsTER, STANLEY G. L1sTEn,-and THoMAs BORDEAUX, citizens of the United States, residing at Olympia, in the county of,Thurston and State of Washington, have invented certain new and useful Improvements in Logging-Oar Stakes,` of which the following is a specication, reference being had therein to the accompanying drawings.

This invention relates to improvements in logging-car stakes; and its object is to provide a stake device that may be readily put into place for retaining the logs upon the car and yet be quickly lowered out of operation when the logs are to be rolled from the car with safety to the log-tenders.

Wooden posts inserted in sockets which are attached to the car-body along its sides have heretofore been used for holding the logs on the car, and on account of the stakes of this character being jammed in their sockets by the great pressure exerted by the cargo of logs it has been found impossible to remove the stakes except by chopping them off above the sockets, an operation vnot only requiring considerable time and'expense in furnishing a new set of stakes for each separate haul, but extremely dangerous to the log-tenders. To overcome these and other objectionable features, we provide a steel or iron stake always ready for use, means for locking it in operative position, and means for instantly disengaging the same to drop out of the path of the logs when they are to be unloaded, whatever may be the pressure thereagainst.

In the vaccompanying drawings, where similar numerals designate corresponding parts throughout the several views, Figure 1 is a Vertical front View, Fig. 2 a vertical side view, and Fig. 3 a plan view, of our improved stake device.

The stake is formed of two-pieces,'a wedgeshaped piece 1, tapering from the top to the lower end, and another wedge-piece 2, tapering in a reverse direction to the former, which may be designated as the supplementary Stake and both of which are inserted in the socket 3 of the car.

4 is a key, preferably dovetailed in cross-section, which is inserted through a transverse slot of like section in the back of the supplementary piece 2, that locks'the same, which bears the weight of the main piece 1 on their contact-surface and is itself borne by projecting ends 5 by the aforesaid socket 3. A spring 6 maintains a constant pressure upon the key 4 to prevent the same from creeping or being dislocated by the continual jolting of the train as it passes over the rails.

The stake-pieces 1 and 2 are preferably channeled longitudinal to their length to reduce their weight and also furnish keyways to register with projecting feathers 6 and 7, which are formed on the socket and main stake-piece 1 to prevent any endwise tilting of the pieces. At the top ends of the stakepieces 1 and 2 are projecting ears or lugs 9, adapted to engage with and prevent the said pieces passing entirely through the socket when dropped out of operation.

The device is shown in operation in the drawings by full lines and is thrown out of action by removing the locking-key 4 and giving a tap with a maul upon the top of the piece 2, which by its Wedge-shaped form drops freely to the position shown by dotted lines in Fig. 1, when it will be seen that the piece 1, having no vertical support, will of its own weight immediately drop to release the logs.

The device will be readily understood from this brief description, and it is apparent that changes may be nade in the details of construction without 'departing from the spirit of our invention or sacrificing its advantages.

What We claim as new, and desire to secure by Letters Patent, isl. In a stake device for logging-cars, the combination with a socket, of a stake com'- prised of two wedge-shaped pieces mounted in reverse positions in the said socket and means for retaining the said stake at a suitable height for the purpose set forth.

2. In a stake device for logging-cars, the combination with a socket, of a stake comprised of two wedge-shaped pieces mounted in reverse positions in the said socket and a key for retaining the said stake at a suitable height for the purpose described.

3. In a stake device for logging-cars, the combination with a socket, of a stake com prised of two wedge-shaped pieces mounted in re'verse positions in the said socket, said pieces having lugs upon the upper ends thereof, and a key for retaining..r the said stake at a suitable height for the purpose described.

4. A stake device for logging-cars, conlprising a socket having a feather projecting interioriy thereof,a Wedge-shaped piece tapering from the top having a channel or keyway adapted to engage with the said feather and a feather upon the side opposite to said channel, another wedge-shaped piece tapering in a reverse position having a channel adapted to
